Pressure switch Dongs GW 3 A4
The Dungs GW 3 A4 is a mechanical gas pressure control switch designed for monitoring pressure in combustion systems such as burners, heating boilers, and gas-fired equipment. It is specifically engineered for low-pressure ranges, typically from 0.5 to 10 mbar, and delivers reliable performance in both industrial and residential environments thanks to its durable construction. The unit is equipped with an SPDT Single Pole Double Throw microswitch, allowing for integration with control circuits. The switching point can be manually adjusted via a calibration screw, and the device operates effectively within an ambient temperature range of -20°C to +60°C. It is also approved under European standards EN 161 and EN 1643, ensuring safety in gas-powered applications.
Manufactured by the German company Dungs, this pressure switch operates entirely mechanically, requiring no external power supply, making it ideal for pressure-sensitive applications. Its compact design and ease of installation make it suitable for a wide variety of gas supply systems. The GW 3 A4 is built to withstand pressure fluctuations and provides consistent performance under varying environmental conditions. With international certification and compliance, it serves as a critical component in gas safety control
